Abstract

Thiophene-Based Materials for Optoelectronics NU 2001-049 Inventors Tobin J Marks* Antonio Faccetti Short Description Synthesis of several thiophene-based organic molecules for fabrication of n-type semiconductors #devices #optoelectronic #materials #electronic Abstract Northwestern researchers have developed novel thiophene-based materials that can be used to fabricate n-type semiconductors for a variety of electronic devices. The substituted thiophene-based materials are produced via simple procedures in a high yield, which is essential for device manufacturing. Furthermore, these materials are easy to functionalize, which allows scientists to customize their properties. For instance, fluoro-azine substitution has been shown in the laboratory to enable modulation of optical gap, absorption-emission maximum and quantum yields, both in solution and in thin films. Nonetheless, favorable chemical and thermal properties are exhibited by all of the thiophene-based substituted organic materials generated by the Marks group. These materials are expected to make a significant contribution to design and manufacturing of solar cells, thin film transistors and diodes as n-type semiconductors with high field effect transistor mobilities (~ 0.01cm2/Vs) are rarely found.
